Elevate when the mouse hovers over the button

Question

Elevate when the mouse hovers over the button

My current task involves increasing the bottom-padding of a span when the mouse hovers over a button. Here is the button code:

<button class="btn btn-success btn-circle" id="myBtn" title="Go to top">
    <span id="move" class="fa fa-chevron-up"></span></button>

To accomplish this, I attempted to create a class with increased bottom-padding (13px) using JavaScript.

Here is the class I created:

.set {
        padding-bottom:13px;
    }

And here is the JavaScript code I used:

window.onload = function() {
        document.getElementById("myBtn").onmouseover = function() {
            document.getElementById("myBtn").classList.add(" set");
        }
    }

Unfortunately, this approach did not yield the desired results. Can anyone provide assistance? The objective is to revert the span's bottom-padding back to its default value of 3px when the mouse is no longer on the button. Thank you!

To achieve this effect, you can utilize CSS in a simple way:

.btn-circle:hover span{
 padding-bottom:13px;
}

Explanation

 :hover // triggers when mouse enters an element

Make sure to use padding-bottom:13px; instead of padding-bottom=13px;

One way to address this issue is by implementing CSS3 techniques. You can refer to this link for more information: https://www.w3schools.com/css/tryit.asp?filename=trycss3_transition1. Instead of adjusting the width of the element, consider modifying the padding-bottom value.

Eliminate the space in your class assignment from " set" to "set". To avoid repeating the getElementById method on the DOM, you can assign it to a variable like elem.

window.onload = function() {
  var elem = document.getElementById("myBtn");
  elem.onmouseover = function() {
    elem.classList.add("set");
  }
}

.set {
  color: red;
}

<button class="btn btn-success btn-circle" id="myBtn" title="Go to top">
<span id="move" class="fa fa-chevron-up">someIcon</span></button>

It's a bit unclear, but I believe you're trying to move the inner span upward without increasing the padding of the button itself. Here's a possible solution:

#myBtn:hover #move {
    position: relative;
    top: -3px; // adjust as needed
}

You could make this movement animate smoothly like this:

#move {
    position: relative;
    top: 0px;
    transition: all ease-in-out 0.3s;
}   

#myBtn:hover #move {
    position: relative;
    top: -3px; // adjust as needed
}

Just a heads up, there are other responses suggesting the use of `padding-bottom`, but keep in mind that it will impact the parent's size. Using `top` in combination with `position: relative` is a more stable approach.
